It is 28.3 cm, approx.
Doubling the radius doubles the circumference.
56.549 cm
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
Diameter of a circle = circumference/pi

The circumference of a circle that is 9 cm wide is: 28.274 cm

Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. Given that the diameter of the circle is 69mm, you can substitute this value into the formula: C = π * 69mm ≈ 216.769mm. Therefore, the circumference of the circle is approximately 216.769mm.
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
Oh, dude, it's like you're asking me to do math or something. So, the formula for finding the diameter of a circle is just dividing the circumference by pi (π). So, in this case, the diameter would be 8 divided by π, which is approximately 2.55. But hey, who's really counting, right?
Circumference of the circle: 2*pi*9 = 18*pi cm
